No Cell Mate for Paris

Paris Hilton has her jail cell all to herself ... for now.

After turning herself over to the authorities late Sunday night, Ms. Hilton is finally behind bars at a county jail in Lynwood. Los Angeles County Sheriff's spokesman Steve Whitmore says the heiress has been "cooperative and calm" since her arrival. Whitmore says Hilton has been booked and fingerprinted, and will be spending the rest of the night in a cell by herself.
